So, I got a bunch o' rattlesnake master that has been seeding itself all over the place. Can anyone answer any of the following:

1. Are its seeds Preen-resistant?....They seem to be.

2. Roots rarely come up, even with careful hand-weeding...is it likely those partly-pulled plants will come right back?

3. Will R-master otherwise be compliant when "herbicided"

Thanks,

Dave,
